The debut of Drew Lock has moved one step closer.
Although coach Vic Fangio has been coy, it’s widely expected that Lock will supplant Brandon Allen on Sunday against the Chargers.
A second-round pick from Missouri, Lock suffered a wrist injury in August.
The 3-8 Broncos are one loss away from their third straight losing season. The 4-7 Chargers need to run the table to have a realistic shot at getting back to the postseason.
